Work in Karbon won't be created by GoProposal until the proposal is signed, accepted and reflected as won in GoProposal. At that point, any line items mapped to Karbon work templates will create your work items based from those work templates (including the assignment of a work type and associated work statuses).
If the client details included a Company Name (i.e. Organization), the work will be created and assigned to the Organization. If the client details do not include a Company Name (i.e. Person), the work will be created and assigned to the Person (individual).
